Crystal structures of N-tert-butyl-3-(4-fluoro­phenyl)-5-oxo-4-[2-(tri­fluoro­meth­oxy)phen­yl]-2,5-di­hydro­furan-2-carboxamide and 4-(2H-1,3-benzodioxol-5-yl)-N-cyclo­hexyl-5-oxo-3-[4-(tri­fluoro­meth­yl)phen­yl]-2,5-di­hydro­furan-2-carboxamide

The structures of two butenolide derivatives are reported. The conformations are differ largely in the orientation of the amide carbonyl atom.

Abstract

The title compounds, C₂₂H₁₉F₄NO₄, (I), and C₂₅H₂₂F₃NO₅, (II), each contain a central nearly planar di­hydro­furan­one ring. The r.m.s. deviation from planarity of these rings is 0.015 Å in (I) and 0.027 Å in (II). The mol­ecules are T-shaped, with the major conformational difference being the O—C—C—O torsion angle [−178.9 (1) in (I) and 37.7 (2)° in (II)]. In the crystal of (I), mol­ecules are linked by N—H⋯O hydrogen bonds, forming chains along [001] while in (II) mol­ecules are linked by N—H⋯O hydrogen bonds, forming chains along [010]. In (II), the tri­fluoro­methyl substituent is disordered over two sets of sites, with refined occupancies of 0.751 (3) and 0.249 (3).

Chemical context  

Butenolides, also known as furan-2(5H)-ones or furan­ones, are a recurrent moiety in more than 13,000 natural products (De Souza, 2005 ▸) and possess different assorted biological applications, exemplified by cytotoxic (Jung et al., 1990 ▸) and anti­biotic (Sikorska et al., 2012 ▸) activities. Likewise, the butenolide derivative Vioxx® is a potent NSAID (non-steroidal anti-inflammatory drug) used for the relief of pain and inflammation (Prasit et al., 1999 ▸) before it was withdrawn from the market in 2004. As a part of our scientific endeavors to access and mimic the complexity and diversity present in naturally occurring mol­ecular scaffolds, the title compounds were synthesized using a Passerini/Knoevenagel sequence and the crystal structures are reported herein. Other multi-component reaction-based approaches towards furan­ones have been reported, but they use limited starting materials. For example, they use unstable phospho­nates (Beck et al., 2001 ▸), aliphatic substituents (Bossio et al., 1993 ▸, 1994 ▸; Marcaccini et al., 2000 ▸), or tricarbonyl inputs (Rossbach et al., 2014 ▸).

Structural commentary  

The mol­ecular structures of N-tert-butyl-3-(4-fluoro­phen­yl)-5-oxo-4-[2-(tri­fluoro­meth­oxy)phen­yl]-2,5-di­hydrofuran-2-carboxamide (I) (Fig. 1 ▸) and 4-(2H-1,3-benzodioxol-5-yl)-N-cyclo­hexyl-5-oxo-3-[4-(tri­fluoro­meth­yl)phen­yl]-2,5-di­hydrofuran-2-carboxamide (II) (Fig. 2 ▸) are similar. The mol­ecules are T-shaped, with the major conformational difference being the O1—C—C—O2 torsion angle. In (I), this torsion angle is −178.9 (1)°, whereas in (II), it is 37.7 (2)°.

Figure 2.

In (II), the amide oxygen atom, O1, is tucked between O2 and H1A, with contact distances to O2 of 2.738 (1) Å and to H1A of 2.54 Å. The central, di­hydro­furan­one ring is nearly planar in both compounds. The r.m.s. deviation of these central rings is 0.015 Å in (I), and 0.027 Å in (II). In (I), the dihedral angle between the furan ring and the p-fluoro substituted benzene ring is 44.66 (4)° and with the tri­fluoro­meth­oxy-substituted benzene ring it is 48.71 (3)°. In (II), the dihedral angle between the furan ring and the p-tri­fluoro­methyl substituted benzene ring is 40.03 (5)° and the dihedral angle with the benzene ring of the benzo[1,3]dioxol-5-yl ring system is 43.06 (6)°. The cyclo­hexane ring of (II) is in a chair conformation.

The –CF₃ substituent of (II) is disordered over two sets of sites. In the major component [occupancy = 0.751 (3)], F2A has a close contact to atom O1 [2.772 (2) Å] of a neighbouring molecule, which is lengthened to 3.093 (6) Å in the alternate configuration i.e. the minor component. Two hydrogen atoms from symmetry-equivalent mol­ecules flank F3B (H2A, 2.72 Å, and H23, 2.57 Å) and prevent rotational disorder from alleviating the close contact. In the minor component, the –CF₃ group deviates from the plane of the aromatic ring, with C25B displaced by 0.36 (1) Å from the mean plane of the aromatic ring.

Supra­molecular features  

In both crystals, N—H⋯O hydrogen bonds connect the mol­ecules into chains which run, in (I) along the c-axis direction (Table 1 ▸), and in (II) along the b-axis direction (Table 2 ▸). The hydrogen-bonding graph set is C(4) in both (I) and (II). The partial packing plots of (I) (Fig. 3 ▸) and (II) (Fig. 4 ▸) illustrate the hydrogen-bonding motifs.

Database survey  

The Cambridge Structural Database (CSD) contains few examples of 3,4,5-substituted furan-2(5H)-ones. A search (CSD Version 5.36, November 2014; Groom & Allen, 2014 ▸) found only one other structure with an amide attachment at the position 5 carbon, TIFXIP (Beck et. al, 2001). For TIFXIP, the O1—C—C—O2 torsion angles for the two mol­ecules in the asymmetric unit are −40.1 and 40.4°, similar to that found in (II), and the O1⋯O2 distances are 2.76 and 2.78 Å. When the search is expanded to include mol­ecules with a second organic substituent on the furan 5-carbon, additional structures are found. In six structures, where only one of the substituents is an amide, the O1—C—C—O2 torsion angle is 180° ± 30° (−150 to 150°); the value of −178.8 (1)° found for (I) falls in this range.

Synthesis and crystallization  

Compound (I): 4-fluoro­phenyl­glyoxal (1 eq., 0.5 mmol), tri­fluoro­meth­oxyphenyl­acetic acid (1 eq., 0.5 mmol) and tert-butyl isocyanide (1eq., 0.5 mmol) were dissolved in DCM (2 mL) and stirred at room temperature for 1 h. After confirming the exclusive formation of the Passerini product (via TLC and LC/MS), the solvent was removed and the crude product was dissolved in DMF (2 mL). Diiso­propyl­amine (DIPEA) (2 eq., 1 mmol, 140 µL) was added and the reaction mixture was heated at 393 K using microwave irradiation for 20 minutes. After cooling and verifying reaction completion (TLC and LC/MS), the crude mixture was directly purified by flash chromatography (EtOAc/hexane 0–100%) using an ISCO TM flash chromatography system to afford N-tert-butyl-3-(4-fluoro­phen­yl)-5-oxo-4-[2-(tri­fluoro­meth­oxy)phen­yl]-2,5-di­hydro­furan-2-carboxamide as a beige solid (67% yield).

Compound (II): 4-tri­fluoro­methyl­phenyl­glyoxal (1 eq., 0.5 mmol), 3,4-methyl­ene­dioxy­phenyl­acetic acid (1eq., 0.5 mmol) and cyclo­hexyl isocyanide (1eq., 0.5 mmol) were dissolved in DCM (2 mL) and stirred at room temperature for 1 h. After confirming the exclusive formation of the Passerini product (via TLC and LC/MS), the solvent was removed and the crude product was dissolved in DMF (2 mL). Diiso­propyl­amine (DIPEA) (2 eq., 1 mmol, 140 µL) was added and the reaction mixture was heated at 393 K using microwave irradiation for 20 minutes. After cooling and verifying reaction completion (TLC and LC/MS), the crude mixture was directly purified by flash chromatography (EtOAc/hexane 0–100%) using an ISCO TM flash chromatography system to afford 4-(2H-1,3-benzodioxol-5-yl)-N-cyclo­hexyl-5-oxo-3-[4-(tri­fluoro­meth­yl)phen­yl]-2,5-di­hydro­furan-2-carboxamide as a yellow solid (61% yield).

For both compounds, crystals suitable for X-ray structure elucidation were obtained by slow evaporation of a solution of the compound in a mixture of ethyl acetate/hexa­nes (1:3).

Refinement  

Crystal data, data collection and structure refinement details are summarized in Table 3 ▸. Hydrogen atoms were visible in the difference Fourier maps for both structures. The hydrogen atoms bonded to nitro­gen atoms which are involved in hydrogen bonding were placed at positions of the electron density peaks and freely refined. All other hydrogen atoms were placed at calculated positions and allowed to ride on their parent atoms: C—H = 0.98 Å for methyl H atoms and 0.95 Å for other H atoms, with U _iso(H) = 1.5U _eq(C) for methyl H atoms and = 1.2U _eq(C) for other atoms.

In (II), the tri­fluoro­methyl substituent is disordered over two sets of sites with refined occupancies of 0.751 (3) and 0.249 (3). The disorder does not correspond to the expected rotational disorder of the –CF₃ group, but rather consists of a deviation, in the minor component, of the central carbon atom out of the plane of the aromatic ring.

Experimental. Absorption correction: SADABS-2008/1 (Bruker, 2009) was used for absorption correction. wR2(int) was 0.0543 before and 0.0350 after correction. The Ratio of minimum to maximum transmission is 0.7899. The λ/2 correction factor is 0.0015.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.

(II) 4-(2H-1,3-Benzodioxol-5-yl)-N-cyclohexyl-5-oxo-3-[4-(trifluoromethyl)phenyl]-2,5-dihydrofuran-2-carboxamide . Special details

Experimental. SADABS-2012/1 (Bruker,2012) was used for absorption correction. wR2(int) was 0.0555 before and 0.0466 after correction. The Ratio of minimum to maximum transmission is 0.8167. The λ/2 correction factor is 0.0015.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.
